About this study

Official title: Randomized Control Study on Surgical Treatment for Middle and Lower Thoracic Esophageal Cancer Patients Without Upper Mediastinal Lymph Node Metastasis Through Left Versus Right Transthoracic Approach

Esophageal carcinoma is an aggressive malignant disease with poor prognosis. Surgical resection remains the most effective method for this malignancy. Although different approaches have been studied for the surgical resection of thoracic esophageal cancer, little evidence has been achieved due to lack of large scale multicenter randomized trials with regard to this issue: whether left transthoracic approach or right transthoracic approach is the optimal surgical approach for treating middle and lower thoracic esophageal cancer without upper mediastinal lymph node metastasis. The purpose of this study is to compare the postoperative local recurrence rate and long-term outcome of esophagectomy through left and right transthoracic approach in the middle and lower thoracic esophageal cancer patients without preoperative upper mediastinal lymph node metastasis.

Read the detailed description

Esophageal carcinoma is an aggressive malignant disease with poor prognosis. Surgical resection remains the most effective method for this malignancy. As to the middle and lower thoracic esophageal cancer patients without upper mediastinal lymph node metastasis, the rational transthoracic approach either through right or left chest has not been clarified to date due to lack of large scale multicenter randomized trials. Although some randomized trials had been finished in single-center, there is no enough evidences that all lower and middle thoracic esophageal cancer patients should be surgically treated throuhg right chest approch. It is widely recognized that left thoracotomy approach(Sweet procedure) is not appropriate in the patients with upper mediastinal lymph node metastasis, because patients can benefit from the right thoracotomy approach, through which upper mediastinal lymph node can be dissected completely and may get a better long-term survival.Therefore,in this study, the enrolled patients are the middle and lower thoracic esophageal cancer patients without preoperative upper mediastinal lymph node metastasis by CT and/or ultrasound, and 10 hospitals will participate this study. Through comparison in postoperative complications and long term outcomes as well as locoregional recurrence between the left and right apppoach, hopefully we can answer the question whether the right or left transthoracic procedure is the optimal approach for treating middle and lower thoracic esophageal cancer patients without preoperative upper mediastinal lymph node metastasis.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Left thoracotomyProcedure or surgery

    Transthoracic approach is the surgical procedure including the open and minimally invasive thoracotomy.

  • Right thoracotomyProcedure or surgery

    Transthoracic approach is the surgical procedure including the open and minimally invasive thoracotomy.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Left thoracotomy and Right thoracotomy in people with Esophageal Cancer, run by Chinese Academy of Medical Sciences at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 20 May 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Long term survival (time frame: 5 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02448979, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 May 2015.
